Description

Technical Field

[0001] The utility model belongs to the field of coal coking and relates to a mobile coke oven dust removal water seal slag removal dredging device. Background Art

[0002] The coke side coke seal of the coke oven is frequently used every day, resulting in a large amount of coke foam at the bottom of the water seal, which is extremely easy to block the sewage outlet at the bottom of the water seal. If you use a stick to directly dredge it, during the dredging process, the stick will push down, and if it is blocked, the coke foam will become more and more solid, making it difficult to dredge. Finally, you can only dismantle the sewage valve, which is easy to damage the valve or flange during the disassembly process. Chinese patent CN216662966U discloses a U-shaped trough slag discharge device for coke discharge from a coke oven, comprising a U-shaped smoke guide pipe, wherein the U-shaped smoke guide pipe is arranged in a U-shaped coke intercepting water seal, a slag discharge port is arranged at intervals at the bottom of the U-shaped coke intercepting water seal, and a slag discharge valve is arranged on the slag discharge port; the device also comprises at least one submersible pump arranged in the U-shaped coke intercepting water seal on one side of the U-shaped smoke guide pipe, the outlet of the submersible pump is connected with the inlet of the guide nozzle, and the submersible pump is used to pressurize the water in the U-shaped coke intercepting water seal and pump it into the guide nozzle; a coke foam impact nozzle is arranged on the water spray outlet of the guide nozzle, which is used to use the water flow pressure to impact the coke foam deposited at the bottom of the U-shaped coke intercepting water seal trough; the outlet pipeline of the guide nozzle is arranged vertically to the bottom of the trough of the U-shaped coke intercepting water seal, and the coke foam impact nozzle is arranged above the bottom of the trough, and a stop valve is also arranged on the guide nozzle.

[0003] The prior art has the following technical defects:

[0004] In the above technical solution, the nozzle is used for stirring, so that the coke foam at the bottom of the tank is discharged from the slag discharge port to solve the problem of coke residue deposition and non-flow. However, long-term stirring not only makes the coke foam discharge smoothly, but also makes the coke foam flow in the coke water seal. Over time, when the coke dust collector moves, it will produce friction with the coke foam accumulated at the bottom, thereby affecting the service life of the coke dust collector. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mobile coke oven dust removal water seal slag removal dredging device.

[0006] The utility model discloses a mobile coke oven dust removal water seal slag discharge and unblocking device, comprising a coke blocking water seal, a coke blocking dust collector, a dust removal pipeline, a slag discharge port and an unblocking water pipe. The coke blocking water seal is provided with a water pump, the water pump is connected with a water supply pipe, the water supply pipe is connected with the unblocking water pipe through a tee, the coke blocking dust collector is fixedly connected with a mobile stirring pipe, the mobile stirring pipe is connected with the tee through a hose, and the unblocking water pipe is located above the slag discharge port.

[0007] Working process or working principle:

[0008] During operation, water is pressurized by a water pump and sprayed through the unblocked water pipe to stir the coke foam at the bottom of the coke blocking water seal to prevent it from accumulating and blocking the slag discharge port. The coke foam is stirred and moves around, which will cause coke foam to accumulate outside the slag discharge port over time. When the coke foam accumulates to a certain extent, it will contact the bottom of the dust removal pipe. Since the coke blocking dust collector is used frequently and moved frequently, it will rub against the coke foam at the bottom. To avoid friction, a mobile stirring pipe that can move synchronously with the coke blocking dust collector is provided on the coke blocking dust collector to spray water and stir the coke foam at the bottom to avoid excessive accumulation, thereby affecting the service life of the dust removal pipe.

[0009] The movable stirring pipe is located on the right side of the dust removal pipe.

[0010] The coke intercepting water seal is provided with a pipe rack matched with the hose, which fixes the hose to a certain extent to prevent the hose from being rolled into the coke intercepting water seal when the coke intercepting dust collector moves.

[0011] The dredging water pipe is connected to the water spray pipe through a reducing joint. The diameter of the dredging water pipe is larger than the diameter of the water spray pipe, so that the water flow passing through the small-diameter water spray pipe has a stronger cleaning ability.

[0012] The water spray pipe is located above the slag discharge port and slightly to the left to avoid water spraying directly on the slag discharge port, which affects the slag discharge efficiency. Water can be sprayed on one side of the slag discharge port to stir the coke foam and avoid accumulation and blockage of coke foam.

[0013] The water delivery pipe is provided with a valve to cut off the water source when the water pump is inspected and repaired.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model reduces the situation of manual dredging and blockage, reduces the labor intensity of workers, and simultaneously adds a mobile stirring pipe to blow away the coke foam at the bottom during mobile work, thereby extending the service life of the dust removal pipeline.

DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figure 1-2 As shown, the mobile coke oven dust removal water seal and slag dredging device described in the utility model comprises a coke blocking water seal 2, a coke blocking dust collector 3, a dust removal pipeline 12, a slag discharge port 6 and a dredging water pipe 9. The coke blocking water seal 2 is provided with a water pump 1, the water pump 1 is connected to a water delivery pipe 11, and the water delivery pipe 11 is connected to the dredging water pipe 9 through a tee 10. The coke blocking dust collector 3 is fixedly connected with a mobile stirring pipe 13, and the mobile stirring pipe 13 is connected to the tee 10 through a hose 4. The dredging water pipe 9 is located above the slag discharge port 6; the mobile stirring pipe 13 is located on the right side of the dust removal pipeline 12; the coke blocking water seal 2 is provided with a pipe adapted to the hose 4. The bracket 5 can fix the hose 4 to a certain extent to prevent the hose 4 from being rolled into the coke water seal 2 when the coke dust collector 3 moves; the unblocking water pipe 9 is connected to the water spray pipe 7 through a reducer 8, and the diameter of the unblocking water pipe 9 is larger than the diameter of the water spray pipe 7, so that the water flow passing through the small-diameter water spray pipe 7 has a stronger cleaning ability; the water spray pipe 7 is located on the left side above the slag discharge port 6 to prevent the water flow from spraying directly on the slag discharge port 6 and affecting the slag discharge efficiency. Water can be sprayed on one side of the slag discharge port 6 to stir the coke foam and avoid accumulation and blockage of the coke foam; a valve is provided on the water supply pipe 11 to cut off the water source when the water pump 1 is inspected and repaired.

[0021] Working process or working principle:

[0022] During operation, the water is pressurized by the water pump 1 and passes through the unblocking water pipe 9 to enter the small-diameter water spray pipe 7, so that it has a stronger cleaning ability to spray water to the slag discharge port 6, and stir the coke foam at the bottom of the coke blocking water seal 2 to prevent its accumulation and blockage of the slag discharge port 6. The water spray pipe 7 is located on the left side above the slag discharge port 6 to prevent the water flow from spraying water directly on the slag discharge port 6, which affects the slag discharge efficiency. Since the coke foam is stirred and moves around, it will cause coke foam to accumulate outside the slag discharge port 6 over time. When the coke foam accumulates to a certain extent, it will contact the bottom of the dust removal pipe 12. Since the coke blocking dust collector 3 is used frequently and moved frequently, it will rub against the coke foam at the bottom. In order to avoid friction, a mobile stirring pipe 13 that can move synchronously with the coke blocking dust collector 3 is provided to move water to stir the coke foam at the bottom to avoid excessive accumulation, thereby affecting the service life of the dust removal pipe 12.

[0023] The utility model reduces the situation of manual dredging and blockage, reduces the labor intensity of workers, and at the same time, a mobile stirring pipe is added to blow away the coke foam at the bottom during mobile work, thereby extending the service life of the dust removal pipeline 12.
